no access to network share using TI8 Rescue CD

Hi,
i started Acronis True Image 8.0 Server for Windows from the bootable rescue cd to restore an image from an archive located on a network drive, but when I try to login to a network computer, it NEVER! asks me for the user name and password. So i can not connect to the share.
I can open the share and the filesystem for 'everyone' this will work, but that's not what i want to do, (security reasons)

- dhcp works
- and browsing works fine i can see all my computers in the domain

Please make sure Acronis Bootable CD is created with the latest build (796) of Acronis True Image Server. If the problem persists please send a letter with the description to support@acronis.com. We will certainly help you with the solution.
